To all whom it may concern:

Be it known that I, F RANK KUBA, aciti- A' pzen of the United States of America, anda resident of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Locks, of which the fol-.

lowing is a specification.

This invention relates to locks adapted to be operated by means of a coin or check and comprises such parts and elements of construction as is hereinafter setfortli in detail while reference is had to the accompanying ldrawings in which the preferred form of my invention is illustrated.

The particular novel features ofthe ini-.

vention and the advantages obtained by the use :thereof will be pointed out later.

In the said drawings Figure l is an insidev View of a lock mechanism embodying my invention, showing the same applied on a door and with parts removed. Fig. 2 is a vert-ical.' sectional view if through the lock. `Fig.,3 is an, inside detail view-showing the l `bolt operating means, the releasing niecha--y niemand related parts. Fig: 4 is a view of the cylinder and the releasing mechanismy in the position when the lock is locked. Fig.

y5 is a horizontal sectional view through the lock. Fig. 6 is a detail view showing the operation of the key. F ig. 7 is a detail view of the key cylinder. Fig. 8 is a detail View oii a small scale of that part of the door to l which the lock is fastened, and Fig. 9 isa detail view showing the means for operat- In the drawings the door, in this instance of metal, is represented at 10 and the same is provided with a `llange l1 which may eX- tend the height of the door or which may 49 be just the same height as the lock. The wall of the locker is indicated at 13 in Fi 5 as haring a corresponding flange throng The lock mechanism is supported lay-,anx

outsidecasiiig comprising the side 16, ends i .17 and 18, and the top and bottom 19, 19. The sides abut the outside of the door but the if? top and bottom projects through the door as best seen in Fig. i. f Cast integral with -the casing are bosses for the. reception of screws i y I to the inside of the door, then a platefit) is as will be explained later, and also the coin chute' Q0 and projections 2l and 22. The

.aie inerenti of the key Cylinder 25. This flat-ter is supportedin a c linder block 26 which rests on-the projection 22 aforesaid, and the said block is provided With a longitudinal cut orslot 27 in 4which lies a stopper 28 in the formof a spring wire fastened at 29 and which has a tendency to press4 inwardly in the block as shown in Fig. 4. The block is further provided with al trip socket 30. A'

Screwedfast togtlie cylinder block is an angular combination plate 31 which projects into andA formsthe upper side of the i aforesaid slot 27'. Thev block is also provided -With aA hollow cylindrical interior in which rests Ythe aforesaidcylinder 25 which is provided-With' a shoulder 32 projecting through .the 'casing 16 and two collars 3 3 and 34:.l 'In the latter .there is a trip socket 35, and a key slot 36 passestlirough the cylinder for its entire,length;V At the inner end of the cylinderitcarries a bolt in 37.

Above..the-.cylinder is secured a ceder lcounter 38.wlichfniay4 beseured to the pro- 4jectioii2l. The figures.: of *the counter may .bevobserved` througlithe end 17'ofthe casing as seen in Fig. l.

Pivoted at-^40 to the casing 16 is the trip lever 41 having a nose 42which by gravity normally enters the trip socket 30 in the cylinder block and a tail 43 which` projects into the coin chute 20.

-Tlie lock ashei'e disclosed is .designed to be operated by nieans of a ten cent piece, and as this-coin orsmall foreign coins .generallyis not heavy enough4 to operate the trip .lever tliereis provided a i'ilunger le to which is Vsecured alhook 45. As seen in Fig.

'the' plunger .passes through a platoft fast to the chute members 2O and also through the top 19 of, the casing. A springr t7 keeps .the plunger up. The coinehute is curved as sliown lin Fig. 9 to prevent tampering and iftlie com 48 is not of sulticient weight to of itself trip the lever ell ythe hook t5 by pressure on tlieplungertivill cari-y the coin down through the chute and into the coin receptacle 49, thus operating the trip lever.

Afteithe above described elei'nents have all been fastened to the casinglt the latter is placed over the opening lllai'id inserted so that the top and bottomproject through vand the Veed-er `counter may be operated from the said pin by means of the forked arm 39. Next the bolt mechanism attached. 'lhis mechanism comprises `the bolt 52 carried by theA rods Around these latter are the coiled springs,54 and the opposite ends of the rods are joined Iby the pull plate 55 against'which the bolt pin 37 pullsto open the lock. through a tension plate 56 between which and the bolt the springs act to force the bolt outward:l Next a holding plate 57 is attachedkto secure the bolt mechanism, and all of the above described parts are secured by the screws 58 passing through the plates 57 and 56 and into the aforesaid bosses 59 on the casing. As the screws 58 are inserted from the inside the screw heads are exposed and to cover these and the one open end of the bolt mechanism there is provided a cover 60 which is slid into place in grooves 61 in the top and the bottom of the casing, the iiange 62 on the cover closing the left end of the lock opposite the door. 4The cover lits very tight in the grooves and to further secure it a screw 63 is .screwed through the boss 64 on the bottom 19 and into the cover Without penetrating the latter as seen in Fig. 2. Lastly the receptacle 49 is inserted from the outside and is preferably secured by a suitable lock, not shown. In this man; ner no screws or other fastening means are visible from either side of the door and no opportunity is afforded for disassembling the lock except by the person having the key to the coin receptacle for the purpose of collecting the money. The tension plate is secured between the plates 56 and 57 by means of tenons 65.

The operation is as follows Normally, that is when the door is open, the parts assume the positions shown in Figs. l and 3 in which it Will be observed that the key is in 4the slot 36 in the cylinder, and that this cylinder slot does not register' with the slot 27 in the block and the bolt is withdrawn. Further the trip lever is in engagement With the cylinder trip socket and thus the cylinder cannot be turned by means of the key or otherwise until the trip lever is tripped as shown in Fig. 4 in Which it ap- .pears from theposition of the bolt pin 37 that the lever has been lifted out of engagement with the cylinder trip socket and that the bolt has been forced outward by the springs 54.

- I n practical use a person will deposit his garments in the locker, then close the .'door, deposit a coin in the chute press down the plunger and thus automatically lock the lock as is clear from the above explanation. He may then withdraw the key and can now at any time open the door. As soon, hoivever, as the door is again opened, the trip lever falls into the cylinder trip socket and The rods pass? the door cannot he again locked until another Icoin has been deposited.

As appears from Fig. (S the key is provided with teeth to tit the particular combination plate in. the cylinder' so that only one particular key will open the lock. Further, way inthe cylinder in order -to push the stop 2T out of the 'cylinder slot', before the cylinder can b'e turned. Hence if tampering with lock is attempted as by inserting a thin wedge or a pocket knife in the slot the turning of the cylinder is prevented first by the: stop and secondly bythe combinationl plate.

The above is thought to clearly explain the construction and operation of the invention. It is to' be noted. ,that immediately upon the loperation of the plunger, or 'upon i l .i the tall ot a com heavy enough, the bolt is automatically forced outward, so that the key 1s only used to open the lock wlth. V arlous changes may of courseV be made without departing from the scope-of the invention and I claim all such changes as may be said 4to come within. the scope of -the l. In a lock the combinationof a. bolt, a key cylinder for operating said bolt, a trip lever adapted to engage said cylinder when the bolt is withdrawn and 'means for autothe key must. be inserted all the mati'cally rotating said cylinder to protractI the said bolt when the said trip lever is acted u on. l
